So, I understand my fellow venezuelans are in NYC, and they're using a new opensource exchange software that seems to be written in Python and still in its infancy called BlinkTrade (just 5 committers, written in Python)
Hopefully with the low transactional volumes they have they won't have to start the rewrite anytime soon. Writing a true exchange requires in my opinion technology that allows for low latency transactions (Java/C++/specialized hardware to process a large amount of orders per second reliably, and that's just the tech side)
So let's suppose they get the capital to have the tech side solved, this part is doable, and I hope they can do it, for Venezuelans actually need this. The huge problem I see, and why I didn't even think of starting an exchange in Venezuela is the part of where you hold the Venezuelan FIAT.
The Venezuelan government is extremely controlling of anything related to money supply. I think in a way they'll both hurt and help Bitcoin in
